Anomcea latielavia, Forst, is sometimes abundant in June and July. It is about 

 one-quarter of an inch long and half as wide ; the abdomen, legs and antennae blackish : 

 the head, thorax and elytra, yellow, with a broad, purplish black stripe at the junction 

 of the latter. The forelegs of the male are very much longer than those of the female, a 

 very uncommon feature of our Chrjsomelidse. 



Of the genera Pachybrachys, Diachus, Paria, etc., there are several species always 

 abundant upon the foliage of willows, and all small cylindrical beetles, one-eighth of an 

 inch or less in length, and often prettily colored.

Another group of abundant and injurious beetles is composed of small species^having? 

 the posterior legs greatly developed, and, consequently, jumping with the greatest agility ,. 

 Their saltatorial powers have earned for them the term flea-beetles. The larger species, 

 Disonycha alternate^ 111., and D. punctigera, Say, are yellowish above, with black stripes, 

 on the wing-covers, and are one-fourth or one-fifth of an inch long. The smaller one&_

 may be readily recognized as relatives of the common flea-beetles which injure grapes^ 

 turnips, cucumbers, etc. Fig. 37 shows the grape-vine flea-beetle, Graptodera chalybea^ 

 and its larva; riddling a leaf.
